To investigate the output of ultraviolet of ShenguangII upgrade project, and study the relevant problem in the harmonics generation in high power laser driver, an experiment with 'Ⅰ+Ⅱ" phase match is conducted in the Shenguang-Ⅱ NO.9 device.The maximal output energy of ultraviolet reaches 2740 J, the maximal fluency exceeds 3.6 J/cm2, and the maximal conversion efficiency is ~63%. The parameters that affect the conversion efficiency are preliminary discussed with experimenal results; the amplitude modulation caused by phase modulation and traverse stimulation Raman scattering is observed in experiment. The design program and parameters for Shenguang-Ⅱ upgrade device are testified by the experimental results.
